```pythondef sum_of_evens(numbers): return sum(num for num in numbers if num % 2 == 0)``` 解决该问题的步骤如下:1. **问题分析**:需要计算一个整数列表中所有偶数的和。核心步骤是过滤偶数,然后求和。2. **判断条件**:判断一个数是否为偶数可通过 `num % 2 == 0` 实现。3. **遍历列...
编写一个Python函数,接收一个整数列表作为参数,返回列表中所有偶数的平均值。 ```python def average_even(numbers): evens = [x for x in numbers if x % 2 == 0] if len(evens) == 0: return 0 return sum(evens) / len(evens) numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]...
Write a Python program to calculate the sum of two lowest negative numbers in a given array of integers. An integer (from the Latin integer meaning "whole") is colloquially defined as a number that can be written without a fractional component. For example, 21, 4, 0, and −2048 are ...

Learn how to calculate the sum of squares of the first N natural numbers using C#. Step-by-step guide with examples.
PythonServer Side ProgrammingProgramming Suppose we have a given integer X, we have to find the maximum value N so that the sum of first N natural numbers should not exceed the value X. So, if the input is like X = 7, then the output will be 2 as 2 is the maximum possible v...
